Design Of The Secure Documents Transmission System In E-Government

Documents transmission system is the core and fundamental system in E-government construction, with its exploitation and application being the main content of the informatization of governments of all levels. On account of the specialty of government work, great emphasis has always been putting on the security and credit of documents transmission. This paper presents two aspects as followed on this question:The first is the question of data security. PKI (Public Key Infrastructure) technique came into form as a result that people gradually had greater demand on information security. Its application scope is quite wide and it became a security technique, which E-government work looked for actively to protect information.The second is the question of the visit control and workflow control. In the documents transmission system, the government organs are the carrier of information decision, tasks execution, administration and supervision in government. The complexity and indefiniteness of government work make the control of documents operation quite difficult.This paper analyzed and compared the prevalent system structure and exploitation means of domestic document transmission system, analyzed the actual work flow and characteristics of government work, discussed in depth the application of role network theory and PKI technique in documents transmission system with the credit and security as the basis. Furthermore, this paper designed a security system for documents transmission, which adapted to the domestic reality, by selecting mature application server, selecting JAVA as the main language and by using controls in client terminal. This system adopted the design of multi-layer structure and package based software design, gave great emphasis on the smoothness of system function expansion, the easy operation for the users in administration and reducing information redundancy, and did well in identity authentication, information integration and undeniability, internal checking and supervision in system itself, and etc..Based on the PKI security authentication platform provided by the 1^st Bureau of Liaoning Province Party Committee, combining with the reality of the documents transmission work requirements of Dalian Party Committee, according to the questions of security function and operation adaptation in documents transmission, this paper made a reasonable deployment of various kinds of security service in PKI technique, offered a fantastic solving program for documents transmission without paper in the office automation of Dalian Party Committee, and has got a good result through practice till now.
